Fig 1: Dietary BBR alleviated the HCD-induced inflammation and ER stress in the intestine of largemouth bass. (A) Expression level of proinflammatory genes. (B) Expression level of anti-inflammatory genes. (C) IL-6 (red) staining images of intestinal sections (bar = 50 µm). (D) Quantification of the IL-6 fluorescence intensity. (E) Expression level of ER stress-related genes. (F) BIP (white) staining images of intestinal sections (bar = 100 µm). (G) Quantification of the BIP fluorescence intensity. Data are represented as means ± SEM (n = 6). *, **, ***, ****Different from each other: *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, NS means no significant difference (One-way ANOVA, Duncan’s post hoc test).
